Tack Master is an invaluable training aid for novice sailors, or those returning to the water who wish to brush up on their points of sail or to refresh the way the wind interacts with your boat.
** LIMITED TIME OFFER : 69p - FULL PRICE £2.50 **
Features:
Interactive Wind Widget
Built in Compass
Points of Sail Indicator
Heel and Centre Board Diagrams
Tack to Tack Bearing Information
The app has two modes:
Race Mode:
The app displays heading information, basic points of sail and tack side (very useful when starting racing) plus sail angles in ideal conditions.
Training Mode:
The app displays the Point of Sail, heel and centre board diagrams along with coloured zones highlighting the points of sail, it also displays the tack side and of course the heading on the floating compass.
This app is designed primarily as a training aid and as such uses approximate calculations for the boats close hauled capability, tack angle and point of sail zones.
It will enable the sailor to interactively work out an approximate plan of action with the wind by pointing the iPhone into the wind and setting that angle, from that point the iphone will assume that the bow of the boat is forwards and will display an approximation of what sail angle and centre board position might be useful at that time.
Use this app to check your planned departure from a jetty or on-board as a crew to back up what you think will happen on the next tack or gybe. (Dont forget a waterproof case!!)
